Using the online compiler

The Compiler is a blank-canvas editor that runs code in any of 12 languages with your own input — no problem or test cases needed.

1. Open /compiler.
2. Pick a language and write code.
3. Add standard input in the stdin box if your program reads input.
4. Press Run to see real stdout/stderr, the exit code, and runtime/memory.

It's perfect for quick experiments, snippets and debugging.
